Johnson, a sophomore, had a solid rookie season as he finished third on the team with a 74.53 scoring average in appearing in 12 tournaments. He recorded a pair of top-five finishes and one top-10 finish. The native of Naples, Florida, carded a 66 on two occasions, tying teammate Sam Weatherhead for the lowest round of the year.
Sharp is the Spartans' most experienced returner and finished last season with a career-best 73.9 scoring average, which was good for second on the team. The senior tied for a team high with three top-five finishes and was the Spartans' top finisher in each of the final two tournaments - the Big Ten Championships and NCAA Regionals.
Walker was limited to just four events last season due to an injury and finished his rookie year with a 77.0 scoring average. He played in the first three events of the season and then returned to take part in NCAA Regionals.
The Spartans begin the new season Sept. 10-11 with the Gopher Invitational in Independence, Minnesota.
